PATENT OFFICE STEEL sronnen Box Application filed Kay 18, 1929. Serial No. 364,280.

This invention relates to improvements in storage boxes and, more especially, such boxes inthe form of units adapted to be stacked one on the other to an indefinite height.

One of the features of my invention is the provision of such boxes which, when so stacked, are all accessible.

By the use of my invention, a large quantity of material can be stored on a relatively small floor space without the necessity of building stationary racks, shelves, or other structures.

My improved boxes are strong and rugged and yet simple in construction and easy to handle.

Other features and advantages of my invention will appear more fully as I proceed with my specification.

In that form of device embodying the features of my invention as shown in the accompanying drawings- Figure l is a view in end elevation of a stack or tier of three units; Fig. 2 is a view taken as indicated by" the line 2 of Fig. 1; and Fig. 3 is a view taken as indicated bythe line 3 of Fig. 2.

As shown in the drawings, each unit includes a substantially rectangular flat corrugated sheet metal platform 10 with op posite marginal'edges bent downwardlyas indicated by 10 10, and provided with inwardly projecting angle irons 11 on their inner sides spaced downwardly some distance from the platform 10. The angle irons may be fastened in any suitable manner-as, for

example, by the rivets 12.

On the platform 10 is mounted a rectangular box or four-walledframe 13 having an 40 open top and bottom, the platform 10 forming the bottom for the frame. The frame may be mounted on the platform in any suitable manner. For example, I have here shown the lower edges of the walls of the as frame 13 bent inwardly to form narrow marginal flanges 13 secured to the platform 10 by rivets 14.

The corrugations in the platform 10 "are indicated by 10 and these are here shown as extendin I transversely of the platform and 1 continue downwardly on the marginal edges 10 a I have here shown the corrugations in the side walls of the frame 13 as extending around the walls thereof in horizontal planes, said corrugations projecting outwardly and being indicated by 13".

A pluralit of units, as shown in Figs. 2 and 3, are a apted to be stacked one on another by resting the angle irons 11 of one unit on the upper side edges of the frame 13 of another unit. Three units are shown so stacked in Fig. 1. It is to be particularly noted that the angle irons 11 are spaced downwardly some distance from the platform 10 so that when the units are stacked, as shown in Fig. 1, each box or frame 13 is accessible from the top and under the plat-' form of the unit next above. That is, articles may be placedinto or'removed from the box or frame 13 of any unit, even though an other unit is resting on the top thereof.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and. arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly-as possible, in view of the prior art.

What I regard as new, and desire to secure by Letters Patent, is:

1. A unit, including a flat platform with opposite marginal edges bent downwardly and provided with inwardly projecting members on their inner sides, and a four-walled frame mounted on the platform, a plurality of said units adapted to be stacked one on so another by resting said inwardly pro'ectin members of one unit on the upper e ges o the frame of another unit.

2. A unit, includin a flat platform with op osite marginal ges bent downwardly an v provided with ang i ie irons on their inner sides, and a four-wa ed frame mounted on the platform, a plurality of said units adapted to be stacked one on another by restm said an'gle irons of one unit on the upa per e ges of the frame of another unit.

In witness whereof, I have hereunto set my hand this 13th day of May, 1929.

CARL L. CLARK.
